Did you know?

Obliterate has been preserved in our language for centuries, and that’s not nothing! The earliest evidence in our files traces obliterate back to the mid-16th century as a word for removing something from memory. Soon after, English speakers began to use it for the specific act of blotting out or obscuring anything written, and eventually its meaning was generalized to removing anything from existence. In the meantime, physicians began using obliterate for the surgical act of filling or closing up a vessel, cavity, or passage with tissue, which would then cause the bodily part to collapse or disappear. Today obliterate thrives in the English lexicon with the various senses it has acquired over the years, including its final stamp on the language: “to cancel (something, especially a postage stamp).”

Word History


borrowed from Latin oblīterātus, oblitterātus, past participle of oblīterāre, oblitterāre "to cause to be forgotten or fall into disuse, make disappear," from ob- "against, facing" + -līterāre, litterāre, verbal derivative of lītera, littera letter entry 1 — more at ob-

Note: The original meaning of oblīterāre was apparently "to wipe out letters, words, etc.," but this sense is not clearly attested in classical Latin. Attested senses appear to have been influenced by oblītus, past participle of oblīvīscī "to forget, put out of mind" (cf. oblivion).
